In this chapter, we will discuss and evaluate the basic 3D physics and mathematics concepts in an effort to gain a basic understanding of Unreal Engine 4 physics and real-world physics. To start with, we will discuss the units of measurement, what they are, and how they are used in Unreal Engine 4. In addition, we will cover the following topics:
The scientific notation
2D and 3D coordinate systems
Scalars and vectors
Newton's laws or Newtonian physics concepts
Forces and energy
For the purpose of this chapter, we will want to open Unreal Engine 4 and create a simple project using the First Person template by following these steps.
